LOAD CONTROLS INC. JULY 16, 2007 Application : Feed Rate Control System The UPC Power Cell and the Action Instruments model G408 Opto-Isolator work together to control feed to grinders, saws, crushers or to effect a valve controlling viscosity in a mixing vessel. The UPC measures motor HORSE POWER and sends a 0-10V or 4-20ma signal to the G408 which is set for an INVERSE function so that an increase in load will slow the feed or control a valve. This CONTROL FEEDBACK will stabilize the process for optimum performance. The offset (ZERO) and gain (SPAN) are set with adjustments on the G408. UPC POWER CELL G408-0001 • Field adjustable scale 5 to 150 H.P. • Adjustable Response Time stops system oscillations or hunting. • 0-10V and 4-20ma Analog Outputs • Works on VFD’s or across the line Starters For technical data: www.actionio.com/products/slimpak/g408.html Analog IN + 0-10V 4-20ma IN 41 42 51 v v 11 PWR 9 - 30 VDC(+) 21 Isolated DC/DC Conv. 52 + OUT Analog 10-0V OUT 20-4ma 12 22 PWR Com (-) 9 8 7 L3 .5 “ L3 51 OUTPUT (+) 41 DC INPUT (+) OUTPUT (-) 52 DC INPUT (-) 42 L2 4.14” MOTOR 6 5 4 3 2 1 L2 3.48” INPUT SPAN L1 L1 ZERO ULTRA SLIM PACK G408 1 2 3 4 5 6 7 8 9 DC PWR (-) 12 DC PWR (-) 22 3.54” 11 DC PWR (+) 21 DC PWR (+) DIN Rail Mounted For data sheet or application help : sales@loadcontrols.com LOAD CONTROLS INCORPORATED 53 TECHNOLOGY PARK RD.
